Modern day computer technology has a variety of different computing systems. For instance, different organizations may use a number of different computing systems implemented using any number of different technologies. In some instances, some of these different computing systems may be integrated with one another. Integrating different computing systems may involve various different operations. For example, system integration may include integrating different applications, services, and/or data on the different systems, replicating data between the different systems. Different tools may be used for system integration such as enterprise application integration (EAI) tools, extract, transform, load (ETL) tools, middleware tools, etc.
